I am been involved in 4 marriages including myself where the total guest list neared 600. You would need to invite your siblings families if they are married. Then your father's and mother's family. Their extended family. Your grandfather grandmother's family. Their extended family. Your neighbors, office guys, friends. Both groom and bride and you would have a number near to 600.
